How to Change Weather in Pokemon Pokopia — Rain Dance & Sunny Day

Weather in Pokemon Pokopia is more than just a visual effect — it directly determines which Pokemon appear in your habitats, which materials you can gather, and which special events can trigger. Many players struggle to find weather-exclusive Pokemon because they do not know that weather can be manually changed. This guide explains everything about the weather system, Castform Weather Charms, and weather-specific habitats.

Weather Types in Pokemon Pokopia

There are three main weather types in Pokemon Pokopia, each affecting gameplay in different ways:

  • Sunny: The default fair-weather state. Most Pokemon appear during sunny weather, and gathering efficiency for plant-based materials is increased. Fire-type and grass-type Pokemon are more active during sunny conditions.
  • Rainy: Rain increases water levels in ponds and rivers, enables fishing at new spots, and causes mushrooms and moss to appear. Water-type Pokemon like Squirtle and its evolution line become more common, and certain habitats only activate during rain.
  • Cloudy: An overcast sky that is neither sunny nor rainy. Some Pokemon exclusively appear during cloudy weather, including several ghost-type and psychic-type species. Cloudy weather also increases the chance of finding rare items in sparkle spots.

Castform Weather Charms

The key to controlling weather in Pokemon Pokopia is the Castform Weather Charm system. Castform is a unique Pokemon that changes form based on weather conditions, and the game uses its forms as the basis for weather-changing items called Weather Charms.

There are three Weather Charms, each corresponding to a Castform form:

  • Sun Charm (Sunny Form): Activating this charm forces sunny weather in your current area. The sun icon appears in the top-right corner of your screen when active.
  • Rain Charm (Rainy Form): Activating this charm triggers rainfall. Puddles form, rivers rise, and water-type Pokemon spawns increase dramatically.
  • Cloud Charm (Normal Form): This charm brings cloudy, overcast conditions. It is the rarest of the three charms and often overlooked by players.

How Weather Charms Work

Weather Charms function as toggle items. When you use a charm, it flips the weather between the charm's associated type and whatever weather was previously active. For example, if it is currently sunny and you activate the Rain Charm, the weather changes to rainy. Using the Rain Charm again while it is raining reverts the weather back to its natural state.

Important details about charm mechanics:

  • Charms affect only your current area. Moving to a different zone resets the weather to that zone's natural state.
  • Weather changes are instant. There is no transition animation — the environment immediately updates with new visual effects and spawn tables.
  • Charms do not have a cooldown. You can toggle weather as many times as you want without any penalty.
  • Only one charm can be active at a time. Activating a new charm overrides any previously active weather effect.

Getting Weather Charms from Professor Tangrowth

Weather Charms are obtained from Professor Tangrowth as part of the main story progression. You receive the Sun Charm after completing the first chapter of the story, the Rain Charm after the second chapter, and the Cloud Charm after a special side quest that Professor Tangrowth gives you later in the game.

Professor Tangrowth explains the charm system during a tutorial sequence, but many players skip through the dialogue and miss important details. If you are unsure whether you have collected all three charms, check your Key Items pocket in the inventory menu. All three charms should be listed there once obtained.

Weather-Specific Habitats

Two habitats in Pokemon Pokopia are directly tied to weather mechanics:

  • Rain Dance Site: This habitat activates only during rainy weather. It requires water features, rain-collecting items, and wet-terrain decorations. When active during rain, it attracts water-type and electric-type Pokemon that are otherwise very rare.
  • Sunny Day Site: The sunny counterpart to Rain Dance Site. This habitat requires sun-related items like sundials, solar panels, and heat lamps. When active during sunny weather, it attracts fire-type and grass-type Pokemon with boosted spawn rates.

Building both of these habitats in the same area gives you the flexibility to swap between weather conditions and access different Pokemon pools without traveling to a new zone.

Weather-Exclusive Pokemon Spawns

Certain Pokemon in Pokopia only appear under specific weather conditions. Here are some notable weather-exclusive spawns:

  • Rainy weather: Lotad, Surskit, Poliwag, Goomy, and Goodra. These Pokemon will not appear in any habitat unless it is raining.
  • Sunny weather: Cherubi, Sunflora, Vulpix, Larvesta, and Heliolisk. Sunny habitats paired with sunny weather yield the highest fire-type spawn rates.
  • Cloudy weather: Ralts, Espurr, Phantump, Litwick, and Misdreavus. Cloudy weather is the hardest to trigger naturally, making the Cloud Charm essential for completing your Pokedex.

Tips for Using Weather Effectively

  1. Before hunting a specific Pokemon, check our Pokemon database to see if it requires a particular weather condition. This saves hours of fruitless searching.
  2. Build weather habitats in areas that naturally support that weather type. A Rain Dance Site built in a naturally rainy area gets bonus spawn rates compared to one built in a desert zone.
  3. Use weather changes to farm specific materials. Rainy weather spawns mushrooms and moss, sunny weather boosts berry growth, and cloudy weather increases rare item drops from sparkle spots.
  4. Remember that weather affects the entire area, not just your habitats. Wild Pokemon in the area also change based on weather, so toggling weather can help you encounter new species even without building a habitat.

Mastering the weather system in Pokemon Pokopia is essential for completing your Pokedex and building every habitat. With the three Castform Weather Charms and strategic habitat placement, you can access every weather-exclusive Pokemon and material in the game.
